The red '03 diesel seems nice, but since it is an '03 diesel, confirm that it has the older 7.3L diesel, and NOT the 6.0L diesel. '03 was the transition year so some have one engine and some have the other.
The first year or two of the 6.0L diesel were plagued with problems on many Ford trucks. If it has the 6.0L, personnaly I would avoid it. If it has the 7.3L engine, I think there's a premium on that, and coupled with the low miles, I think it's a decent but not great price.
